When I was 7 I spent a few moments feeling guilty that my lack of organisation had pushed my father into swearing in frustration (muttering under his breath "I've been dashing around like a blue-arsed fly all morning")
so I'd say I probably had a non-abusive background 
People would shout every now and again. I don't recall my parents shouting at each other.
We had a decent-sized house which was no worse-equipped than most people in the seventies (except for a telly) but had very little spare cash and relied on hand-me-downs.
When school interactions tipped over into meanness and bullying my parents were totally unequipped to deal with it. (As an example, we were all shocked to discover that "just shows how badly you've been brought up!" was not the crushing put-down we'd been led to believe.)
Two of my sisters had issues following an academically-able older sister through school - both were bright (decent degrees, sufficiently successful careers now) but always felt they were judged as not living up to expectations. (Didn't help that my mother saw comments like "so what happened to the other two percent" as encouraging a child to perform better...) Practically all of us had a problem with not knowing How To Learn.
Most of us had issues over relationships and sex - combination of church family, parents who ignored The Sixties because they were in baby mode throughout, aunts' and uncles' hurried marriages all ending in divorce, and a (never formally diagnosed but generally accepted) tendency to AS behaviours.
One of us had (has?) an eating disorder. Most of us use food as a source of comfort and interest.
As adults we get on ok (note I'm 3 hours north of the family home, another sister 3 hours south-west). We've overcome the various resentments and kept hold of the enjoyment and love.
When we were younger D1 was the dreamy one we would laugh at, D2 was the one who spent money like water and lost her key, D3 was responsible and hardworking but needed careful handling, D4 was Weird and would read a book no matter what she was supposed to be doing, D5 had a temper and needed to watch her weight, and S was selfish and overindulged and far too Worldly for his own good (none of that is true, btw, or at least no more than any of the rest of us).
Worst thing that happened growing up? Hm. We'd probably all say something different, because nothing particularly bad happened to the family. Deaths of grandparents obviously affected my parents emotionally but impact on family life was minimal. Dealing with my grandmother's last years with dementia was stressful, as was my other grandmother's life after her stroke. My mother's death happened when we were all adults.
